myBackware is a set of scripts that create a
regular set of database dump files for the
disaster recovery of MySQL servers. It uses
MySQL's mysqldump to create backups as either a
filesystem-stored snapshot or as an email
attachment. Either method has the option to
compress and GPG-encrypt the dump file.

mylvmbackup is a Perl script for quickly creating
backups of a MySQL server's data files. To perform
a backup, mylvmbackup obtains a read lock on all
tables and flushes all server caches to disk,
makes an LVM snapshot of the volume containing the
MySQL data directory, and unlocks the tables
again. The snapshot process takes only a small
amount of time. When it is done, the server can
continue normal operations while the actual file
backup proceeds. The actual backup can be
performed by using tar, rsync, or rsnap.

Openduckbill is a simple command line backup tool
for Linux. It is capable of monitoring files and
directories marked for backup for any changes, and
transferring these changes either to a local
backup directory, a remote NFS exported partition,
or a remote SSH server using rsync. It can either
maintain an exact copy of the source at the backup
destination, or maintain both current and previous
versions of the source at the backup destination.

CD-R/W discs can be written with a technique called packet or incremental writing. This allows transparent and buffer-underrun-free recording for CD recorders that support this method. No more mastering of .iso images; just mount your CD-ROM read/write and copy files directly to it.

pbackup is a small utility for backing up and
restoring file permissions on GNU/Linux and
compatible Unix-based systems. It enables you to
store the current access permissions from any part
of the file system to a local file. This file can
later be used to restore modified access
permissions if needed.
